Mozart FM Transmitter, published on 26 Nov 2025. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66252 exists.\n\nAffected product: DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-66252/ (Markdown: https://insights.sbomify.com/CVE-2025-66252/index.md)","id":"CVE-2025-66252","markdown":"https://insights.sbomify.com/CVE-2025-66252/index.md","name":"CVE-2025-66252","record":{"aliases":["GHSA-5rfv-6ff9-rm8q"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FM Transmitter","requires_auth":"high_privilege","summary":"An attacker can cause a denial of service by triggering an infinite loop in the FM transmitter's file deletion logic when unlink operations fail.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gridware","cpe":[{"product":"mozart_dds_next_1000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_100_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_2000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_3000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_300_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_30_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_3500_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_500_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_50_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_6000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_7000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_1000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_100_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_2000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_3000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_300_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_30_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_3500_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_500_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_50_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_6000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_7000_firmware","vendor":"dbbroadcast"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"Infinite Loop Denial of Service via Failed File Deletion in DB Electronica Telecomunicazioni S.p.A.
